Aroll of paper is 11.8 inches by 78.7 inches you need cover wall that is 28 inches by 85 inches how many rolls of paper is needed

we need 2.56 rolls of toilet paper

i found this my multiplying 11.8x78.7=982.66

next, i multiplied 28x85=2380

and finally, we divide 2380/982.66

and our answer is: 2.56

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
